وَإِن كُنتُمْ عَلَىٰ سَفَرٍ وَلَمْ تَجِدُوا۟ كَاتِبًا فَرِهَـٰنٌ مَّقْبُوضَةٌ ۖ فَإِنْ أَمِنَ بَعْضُكُم بَعْضًا فَلْيُؤَدِّ ٱلَّذِى ٱؤْتُمِنَ أَمَـٰنَتَهُۥ وَلْيَتَّقِ ٱللَّهَ رَبَّهُۥ ۗ وَلَا تَكْتُمُوا۟ ٱلشَّهَـٰدَةَ ۚ وَمَن يَكْتُمْهَا فَإِنَّهُۥٓ ءَاثِمٌ قَلْبُهُۥ ۗ وَٱللَّهُ بِمَا تَعْمَلُونَ عَلِيمٌ
If you are on a journey and cannot find a writer, then a retained pledge [shall suffice]. And if one of you entrusts [an asset] to another, let him who is trusted deliver his trust, and let him be wary of Allah, his Lord. And do not conceal your testimony; anyone who conceals it, his heart will indeed be sinful, and Allah knows well what you do.
